and as we've been finding here with the "deathwith dignity act", and the medical marijuana law, even if you get the laws changed ashcroft and co. will still try to override what the people want.
atempts have been made to pull the ability to write perscriptions for for DR's who participate in either. so far without sucsess but they aren't giving up.
aparently another trick they are using to get around the Oregon law is that while people who are legal licensed to grow marijuana (either those with perscription, or licensed providers each allowed to posses 3 mature plants and 4 imiture plants) they have to allow police to inspect at any time (much like the atf does if you have a licensed personal use still). last winter what some counties where doing (salem area as I recall, I know a couple licensed growers) was allowing federal drug officers to come with for inspections (sort of a 'ride along' thing), they'd do the inspection and leave and then the fed would use what he saw as grounds for a warant on a federal charge. (disclaimer-however, I have not seen this in the news, like I said I know a couple licensed growers who are members of groups, aparently this has happened to some of the people in these groups, and I've heard the same story from more than 1 source)
so even if you vote out stupid laws doesn't mean they wont still try and find someway to still enforce them.
